Quagga RIPd information disclosure
RIPd in Quagga does not honor version control for REQUEST packets.
Quagga will respond to these packages for RIP versions which have been
disabled, or require authentication. This could cause Quagga to leak
information about the network to a remote attacker.
This issue also affects FC4
quagga-0.98.6-1.FC5 has been pushed for fc5, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
